Explanation of the invention (4) The processing machine guide of this implementation mode includes a magnetic levitation system for one month, the superconducting magnetic levitation system levitation guide winding 6 4. Induction power integrated low-temperature capacitor (Figure not shown) Show). The drive winding 62 and the chute 40 are on both sides; the induction power integration equipment and the power integration equipment include the power integration winding. The iron and the suspension-oriented superconducting magnet are composed of three parts at the bottom of the slide 50 (not shown). The sliding of the guide rail of the processing machine generates a moving electromagnetic wave by providing the sliding with the sliding seat at a frequency equal to the sliding speed of the sliding seat 50. At this time, the sliding seat 50 — the magnet is attracted by the driving winding provided at the front of the sliding groove 40 and installed. At the rear end of the slider 50, the other end of the drive winding 6 2 is arranged in the slot 40, pushing the slider 50 to slide. The slider 50 slides each of the three-phase alternating current directions of the drive winding 6 2 to change the drive winding. The current direction of 6 2 can be maintained. In this embodiment, the frequency and voltage adjusted by an electric energy converter can control the suspension of the slider 50 sliding processing machine guide, and the superconducting magnetic repulsion is guided by the suspension guided superconducting magnet 50. The relative movement between the winding and the winding 64 generates a levitation force. The floating guide superconducting magnet is installed on the sliding seat 50. The bottom sliding seat 50 is at a certain speed in the sliding groove 40. The sliding groove 40, a sliding seat 50 and a super Including a drive winding 6 2, a device (not shown) and a liquid nitrogen suspension coil guide winding 6 4 is installed in the sliding seat 50, the inductive and inductive power integrates superconducting magnetism; the liquid nitrogen cryogenic container 6 2 sets of three-phase AC I terminals on both sides of the slot 40 The generated electricity integrates the generated electricity through a drive winding and transforms it once, the speed at which the traction slide 50 flows into the drive winding. The floating levitation unit is installed in the chute 4 0, and the undulating nitrogen in the sliding seat 50 is stored in the driving winding 6 2. The superconducting magnet is integrated by the magnetic force in the chute 4 0 to integrate the electromagnetic force of the superconductor. In group 62, the inflow is continuously gliding, and in group 62, the AC power system floats by using the floating guide provided. In the storage tank, when the slide seat 50 is suspended

Floating guided superconducting magnets ιν + + f ^ B ^ With the tortoise flow, the floating guided superconducting magnets generate strong h, two or two, 'field / renal seat 50 0 is close to the suspension set on both sides of the chute 40. The electromagnetic field generated by the suspension-oriented superconducting magnet of the sun and moon 50 and the sun-guided superconducting magnet is wound around 64 phases, and the levitated guide winding 64 cuts the electromagnetic field, and its magnetic f = ik 着 / 骨 座 5 〇 The change of the glide will generate an induced current. The electromagnetic field generated by the inductive rapid current is opposite to the magnetic field of the suspension-guided superconducting magnet provided on the slider. A repulsive force is generated between the two electromagnetic fields. When the sliding speed of the slider 50 increases to reach At a threshold value, the repulsive force is greater than the gravity of the slide 50, and the slide 50 is suspended. Because of the super curtain magnetism; the resistance value of iron is zero, and the magnetic field strength generated by it is relatively large, and a strong electromagnetic repulsive force is generated between the floating guide winding 64 of the sliding groove 40, which makes the sliding seat 50 floating. When the levitation height of the slider 50 is reduced, the distance between the levitation guide superconducting magnet and the levitation guide winding 64 is reduced, and the current of the levitation guide winding 64 is increased, and the repulsive force is increased, so that the levitation height of the slider 50 is increased. . The suspension height of the slider 50 is related to the sliding speed of the slider 50. The greater the sliding speed of the slider 50, the greater the repulsive force and the higher the suspension height. There is an initial suspension speed for the suspension of the slider 50. If the sliding speed of the slider 50 is lower than the initial suspension speed, the suspension force will not be able to support the slider 50 suspension. The initial levitation speed of the slider 50 can be achieved by means of an applied thrust. When the sliding seat 50 deviates from the centerline position of the sliding groove due to a lateral force, the floating guide superconducting magnet provided on the sliding seat 50 will cause the floating guide winding 64 deflected to the side of the sliding seat 50. The enhanced reverse induction electromagnetic field, corresponding to the floating guide winding 64 on the other side, produces a weakened induction electromagnetic field in the same direction. The two induction * magnetic fields will generate / electromagnetically guide the restoring force to balance the slip.

im 200424033 V. Description of invention (6) The lateral force of seat 50. This pushes the slide 50 to return to the center line position of the chute 40. The superconducting magnet system YBaCu0 used in this embodiment, wherein the ratio of YBaCu is 2: 3: 7, and its chemical formula is Y2Ba3CU70x. The superconducting The magnet can also be made of super-conducting wire made of ultra-fine Qin alloy multi-core wire embedded in the copper bus bar.

The sliding seat of the guide rail of the processing machine in the chute is magnetically suspended in the non-processing stage to achieve frictionless sliding, which can effectively increase the return speed of the slide, save the return time, and improve the processing efficiency of the processing machine. In addition, due to the slide 2 〇There is no friction with the base edge 10, which can prevent the guide from being damaged due to the friction of the return stroke and reduce the precision of the guide. Those skilled in the technical field should easily know that the guidance system of the magnetic levitation guide can realize the guide of the guide rail by installing a mechanical guide device on the slide seat, and the side guide auxiliary wheel is used to interact with the side of the chute (rolling friction ) To generate a restoring force. This restoring force is balanced with the lateral force generated when the carriage is running, so that the carriage moves along the center line of the slide groove. Or install a special guide superconducting magnet on the slide base, and connect it to both sides of the slide groove.

Magnetic repulsion, which is balanced with the lateral force of the carriage 'to ensure that the carriage maintains the correct gliding direction. This guidance method avoids mechanical friction. As long as the current of the guide coil of the chute is controlled, it can ensure that the slide seat maintains a certain lateral gap. In addition, the two magnetic suspensions described in the present invention are: . Such as 雔 V changes, as shown in the fourth A picture; twin brothers four B picture; dual phase combination. If the double V is small, it is shown in the fourth D diagram. Type, as shown in Figure 4C; and double semicircle 孓 ， I 刺 之 要 # In summary, this 噔 mingming is in line with the invention patent ’
